Just what are these Directors cut episodes?
They are extended versions of episodes 21-24.
Each episode has between 2-6 minutes of new scenes added, some quite noticeable, some not.
All in all, they improve the storytelling and flesh out some of the characters more then the original TV episodes.
They also set the stage for End of Evangelion to a greater extent then the originals.
"Which ones should I watch?" Watch these ones. The original 21-24 are quite pointless after these became available.
Since the Eva timeline is as twisted and evil as Anno`s mind, heres the order in how to view the show once and for all:
-Episodes 1-20.
-Director`s cut eps 21-24.
-Episodes 25 & 26.
-End of Evangelion.
What not needed to watch: (As in wont contribute anything to the storyline)
-Death: Was only made to whip up the fanbase before the cinematic release of End of Evangelion.
It is a 1hr recap of episodes 1-24, with some 5 minutes or so of new footage, most of it also in the Directors cut eps.
Completely useless.
-Rebirth: This is just the first 30 or so minutes of End of Eva.
Was attached to Death in order to whip up the fans before the cinematic release of End of Evangelion.
Completely useless once you get End of Eva. (Was never encoded as it was not remastered in the first place, thank God.)
-Old versions of eps 21-24: Who needs these when the DC eps are available?
Was only included in the release because some fanboys surely wouldnt been able to sleep without them.
